DIR-AFT-LUG FOR RAILWAY-CARS.

Specification of Letters Patent.

Patented Apr. 25, 1916..

Application filed November 28, 1913. Serial No. 803,555.

To all whom it may concern Be it known that I, JAMES R. CARDWELL, a

citizen of the United States, and resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Draft-Lugs for Railway-Cars, of which the following is a speciattachment'to the draft arms or sills of a railway :car for receiving stresses incident to draft and bufling. Its object is to provide for increased strength and efficiency, and it consists in a structure as hereinafter described, and as illustrated in the accompanying drawings, in which I Figure 1 is a face view of the lug; Fig. 2 is a' sectional view on the line 22 of Fig. 1; and Fig. 3 is a sectional view on the line 3-3 of Fig. 1.

The improved lug is made of cast metal,

'and'oomprises a flat body portion 10 adapted to lie against the face of the member, such as a draft armor draft sill,to which it is to be attached; This body portion is provided with rivet holes 11, as many in number as 'may be desired, nine being shown. The body portion is provided at one end with an-up standing flange or shoulder 12, for engagement by the follower of a draft gear, and this shoulder is reinforced by-longitudinal flanges 13, 1 1, at the top and bottom of the body portion, such flanges decreasing in height toward the opposite end of the lug.

-Tl1e longitudinal central portion of the body portion 10 of the lug is looped upwardly to form ,a further reinforcing rib 15 extending backwardly from the shoulder 12, and diminishing in height to its opposite end, this loop terminating some distance from the farther end of the lug. Webs 16, 17, unite the forward ends of the ribs 13, 14:, 15, in line with the outer edge of. the shoulder 12.

The lug as described, while being comparatively light, is of great strength.

I claim as my invention- 1. A draft lug of cast metalcomprising a body portion haying bolt holes, a shoulder, a central shoulder reinforcing rib in the form of a loop in.the body portion extending obliquely from the outer margin of the shoulder backwardly to the body portion, shoulder-reinforcing flanges at the top and bottom of the body portion, and webs uniting the rib and flanges at their juncture with the shoulder.

2. A lug comprising a plate, a shoulder upstanding at one end of the plate, a longitudinally straight brace in the form of a plate extending obliquely from the outer margin of the shoulder to the body of the plate, and Webs uniting the side margins ofthe brace with the plate.
